4.3.1 Positioning the Auger 4.3.2 Operating the Auger 1. Ensure your tractor circuit is engaged in the correct direction prior to engaging the auger diverter valve. 1. Ensure that all screens and shrouds are in place and that the cleanout gate, on the bottom of each meter, is closed. NOTE: If remote does not operate properly use manual levers provided as backup control.
4.4 Fill Conveyor 4.3.4 Auger Transport Position NOTE: Fill auger should always be secured for transport, no matter how short the distance. Clean out auger prior to transport or storage. 1. Position the auger so that the tube is resting on the locking mechanism at the back of the aircart. In TBH configurations only, the hopper can be rotated down for transport. NOTE: Aircart lids must be closed and sealed for accurate metering. If metering is erratic, ensure tank lids are closed properly. 2.
4.4.1 Positioning The Conveyor 1. Ensure the tractor circuit is engaged in the correct direction prior to engaging the conveyor diverter valve. If circuit is already engaged, direct the fan diverter valve to the conveyor position from the fan setting. Use the remote provided to move the conveyor in and out of transport. 4.4.2 Operating the Conveyor 1. Ensure that all screens and shrouds are in place and that cleanout gate on each meter is closed.
4.4.4 Conveyor Transport Position 4.5 Bag Lift 1. Latch down the conveyor hopper then fold it up on top of the conveyor tube. Be sure to secure it with the tie down strap supplied. If equipped, the optional bag lift can be used for transporting bagged agricultural product from the ground to the top of the air cart. The bag lift has a maximum capacity of 550 lbs. or ten bags of canola (50 lb. bags). The bag lift runs off the same hydraulic circuit as the auger or conveyor.
4.6 Metering Roller The metering roller is provided in each compartment. The roller is divided into replaceable sections which can be replaced if damage occurs. If there is a damaged section the product gate above the roller can be closed to facilitate changing without emptying the tank. The meter roller can then be removed and repaired, quickly, without product spillage. 4.6.2 Meter Roller Selection Guide NOTE: Ensure roller gate is reopened to commence seeding.
4.8 Seed Hawk® Pressurized Metering System 4.9 Checking Air & Product Flow The test procedure outlined below serves as a guideline for ensuring proper fan speed for effective delivery of product: 1. Remove hose(s) from an outside opener and temporarily attach to the frame of the seeder with the hose looping no more than 12 in. (300mm) below the frame. 2. Begin seeding at normal field speed and observe distance product discharges from hose(s) attached to the frame.
5.0 Maintenance 5.1 Maintenance Schedule Check Item Clean Lube NOTE: The bearings on each Stainless Steel meter are sealed. DO NOT GREASE THESE BEARINGS.
5.2 Storage Prior to storage remove all product from tanks, meters, and fill auger (or conveyor). Also, ensure that the meters are thoroughly vacuumed or washed. If the aircart is washed be sure to dry the system out afterwards by opening the lids and running the fans for 30 minutes. This will prevent damage occurring from ice buildup, and prevent product sticking to wet components which creates blockages. When stored outside tightly cover the fans to seal water out of the airstreams.
